Description

" A pncaeoa filed Novemher 10,1926." Saa m mos 1 My invention relates toz new useful improvements in a jar-lifter,'and has for1- its objects to produce a lifter which will} positively grip and hold the jar and: which will release the jar when desired. Another object is to I make a lifter: that-will be inex-.

pensive to manufacture, and assemble, and 'which will not readily get out of order. Other objects and advantages will be apparent from the following description and the accompanying drawings inwhich holding fast a jar; and Fig. 2 is a. perspec- V tive view of the lifter with the jaws 'spread apart. i j

Simllar numerals refer to slmllar parts in the two views.

. The lifter shown is constructed of wire,

having'a substantially vertical member 1,

the upper portion of which is formed'intof, a handle 2. At thelowerend of the'vertical I member the wires are looped to form eyes through which bolt. 3 is passed. Belowthe bolt-the wires are bowed outwardly to leave form a ,jaw 4 to securely fit around a jar neck. An oppositely bowed member 5, with I an oppositely concaved jaw 13, has the upper part looped to form eyes through which bolt 3' also passes, thereby pivotally mounting member 5.

' has a finger eye 8, and fifrom there the sides 9 of the member surround the vertical member 1 to accurately and easily slide thereon. The free ends of the sliding member serve as pins 10 to operate in slots 7 so that on the vertical movement of the member, the jaws will be alternately spread and drawn to gether. The operating member has a spring 11 to hold it down. r

After 'the'parts' are formed, bolt 3 is put v I in place, the sides of the vertical member 1' are squeezed together and the operating member put in place, then the spring may be attached, or the spring couldbe formed and put on prior to the attaching 'of'the operating member to vertical member 1.

, .Due to thevertical position of the handle and the bowed member 5 swinging from a pivot, the jaws tend to swing together,

' JA -wees The upper parts oft-he wire forming member' 5 are bent into upwardly and outwardly directed levers 6 with the. ends bent back on themselves to form slots 71 7 The vertically sliding operating'member jar, the'i'weight of the jar tends to draw tlie wiith'out otheninfluence, iand since there s =.1sbut one pivot point and that between-and above the bearingpOints of theijavvs on the jaws together,i and the-greater Jthat'FWeight';: the greater .iith'at 'tendency, so long ,5 as no sl1ding"tendency between the jaws andjar p a is present. a v In operationthe handle is gripped,- t-l1e eye 8 pulled up, whichpulls "up pins 10, which in turn move up levers 6 and the aws Figure 1 is a perspective view'of the lifter are thereby opened.
